Wiz Khalifa has confirmed that he is engaged to the model Amber Rose. He announced via his Twitter feed yesterday "She Said Yes!!!" along with a photograph of Amber's engagement ring, a stunning large diamond set into a slim gold band. Khalifa later added "Love is everywhere." Amber responded by posting a message on her own Twitter account that read "He has made me the Happiest Woman in the World!!!!" accompanied by the same photo that Wiz had posted earlier.Wiz and Amber were spotted out together at the Grammy awards on February 12, 2012, looking every bit the perfect couple. Wiz had been nominated for the Best Rap Performance award for Black and Yellow but lost out to Jay Z and Kanye West's 'Otis. The loss will have been a blow to Khalifa, not least because Amber famously dated Kanye West, who allegedly cheated on her with Kim Kardashian. In fact, make that a double blow, because he also lost out on the Best Rap Song category for 'All of the Lights,' which also featured Kanye.
